To all whom t may cof/10cm Be it known that l, VICTOR A.. LANG, a citizen oi the United States, residing at North Fort Worth, in the county of Tarrant and State of rllexas, have invented certain new and useful improvements in Gage- Cocks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and yuse the same.

This invention relates to new and useful improvements in a gage cock and one of its objects is the provision of a device of this character', which shall be simple, durable and eilicient, and which may be manufactured and sold at a comparatively low cost.

Another object of this invention is to provide a valve seat, having vbeveled valve engaging surfaces or faces upon each side thereof, whereby the valve seat may be readily reversed when the valve engaging surface or face upon one side has become worn.

A further object of this invention is to provide a valve casing of a pair of sections and having the valve seat of such a construction that the pair of sections of the casing will hold the valve seat against accidental displacement.

lNith these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement oi' parts .ns will be hereinafter Jmore ully `described and claimed.

For a complete understanding ci my invention, reference'is to be had tothe following description and accompanying drawing, in which Figure 1 is a fragmentary front elevation of a feed boiler gage, illustrating my iii-- vention applied thereto. Fig. 2 is a longitudinal sectional view of my device, Fig. 3 is a similar view, illustrating modiied 'form of valve seat, and Fig. al is a detail sectional view illustrating the construction of the valve seat inthe preferred form.

Referring in detail to the drawing, thel numeral 1 indicates a valve casing, consist- .ing of sections 2 and 3. The section 3 is provided with an enlarged squaredportion 4, whereby the section may be gripped by a Wrench. One end oi the section 3 is provided vvith screw-threads 5 to be threaded Within a steam boiler gage 6. The screwthreaded end of the section 3 is closed'by a wall 7, having a plurality of openings 8. The other end of the section is internally screw-threaded to receive the screw-threaded end of the section 2. The section 2 is closed by a curved wall 9, having a suitable stuffing box 10 to slidably receive a valve rod 11. .The section 2 of the valve casing is provided With an outlet port in which is threaded ay nozzle 12. A bracket 13 is secured to the section 2 and has pivoted thereto, a handle 14, having an arm 15 formed therei on adapted to rest upon the end ofthe valve rod l1.

A valve head 16 is threaded to the inner end of the section 11 of the valve rod and is provided with beveled faces 17 and 1 3. The inner section 19 of the valve rod is threaded to the valve head and eiiqends through a cen- 'trai opening in the Wall 'F A. Pei'iilspring 2O is mounted on theinner section 19 of the valve rod and bears against the wall 7 and the valve headlo.

A substantially circular valve seat 21 is provided with outer and inner beveled engaging surfaces or faces 22 and 23. The engaging surface or. face 22 is adapted to rest upon inclined wall 24 formed on the section 3 of the valve casing. The other engaging surface or 'face 23 is adaptedto bear against the inner beveled end of the section 2 when said section is screwed into the section 3, thus holding the valve seat 21 against movement. The s ring 20 normally holds the beveled face 1g of the valve head 16- against the beveled engagin surface or -face 23 oit' the valve seat 21. en the surface or face 23 becomes worn', the valve seat may be reversed and the o positely disposed surface or face 23 wil be engaged by the valve head 16. The -valve head 16 may alsovbe reversed when worn to bring the beveled face 13 into an. engage- Ynient with the valve seat.

Referring to the modified form illustrated in Fig. 3, it consists of a valve casing constructed of sections 25 and 26 which are provided with their adjoining ends internally screw-threaded. The section 25y is closed at its outer end by a curved wall 27, having a suitable stufiing boX 28 to slidv ably receive a valve rod 29, consisting of outer and inner sections. A. bracket 30 is yconnected to the secured to the section 25 of the valve easing and has pivoted thereto, a handle 8l, having an arin 23; adapted to rest on the valve rod Q9. A nozzle 33 is secured in the outlet port in the section 25 ot' the valve easing adiaeent the curved wall 2T. f

The .sections 25 and are Connected by a. serew-threaded valve seat Si, having an annular flange 237i to space the ends of the seetions 25 and 2U apart. The valve seat 34 is provided with beveled engaging snraces or laees 3U and 3T for the reception of a valve head The valve head 3S is inner end o'l.` the outer seetion of the valve rod and to the outer end of the inner section whieh extends through thel wall lll ot the inner section 2li ol the valve easing. The wall 39 is provided with a plnralittvv ol' openings l0. The valve head is provided with a beveled i'aee ll for engagement` with the l'aee 37, and for an engagement with the laee lo when the valve seat is reversed. eoil spring l2 normall)v holds the valve SSS into au engagement with the valve seal.. 'lhe seetion 21S oil the valve easing is provided with an enlarged squared portion l to lieaeeeived bv a wreinfh for screwing said seetion into a .steam boiler gage. v

lVhile .l have shown and deseribed the preferred embodiment of in v invention, it will be understood that minor changes in eonetruetion, combination and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.

Having thus described what I claim is A gage eoek comprising a Sectional casing, a reversible valve seat held between the sections of said easing, a valve rod extending through one. ot' the sections of said easing and having its inner end screwthreaded, a shoulder formed on said rod adjacent the screw-threaded end and having a beveled face', a valve head having a eentral screw-tln-eaded bore having each end flared and beveled to engage the beveled tace. of the shoulder when threaded to the valve stein. said valve head having valve seat engaging faces, a'perforated wall closing one end of one of the casings, a valve rod slidable in said wall and havingr one end threaded into the valve head, a shoulder formed on the last mentioned valve rod and having a beveled face to eoperate with the beveled faeel of the central bore of the valve head, a spring engaging the wall and the last mentioned shoulder to seat the valve head against the valve seat, and means for operating the first mentioned valve rod.

ln testimony whereof I alliiv my signature in presence of two Witnesses.
